While analyzing some TypeScript code, I stumbled upon a peculiar declaration within a class definition:
constructor(readonly constructorParam : Type) {
// no assignment of constructorParam here
}
Surprisingly, constructorParam is still being used as usual.
Could it be that the constructorParam property is automatically "created and assigned"?
This class is also wrapped in
export abstract class ... extends ... implements ...extends and implement are standard inheritance keywords, and export is typically used for module management).
LATEST UPDATE
After reading through this article, it appears that indeed, constructor parameters marked as readonly are treated in this manner - creating and assigning values by default.
